# Earl of Northumberland

The title of Earl of Northumberland has been created several times in the Peerage of England and of Great Britain, succeeding the title Earl of Northumbria. Its most famous holders are the House of Percy (alias Perci), who were the most powerful noble family in Northern England for much of the Middle Ages. The heirs of the Percys, via a female line, were ultimately made Duke of Northumberland in 1766, and continue to hold the earldom as a subsidiary title.

## History
### Percy family

William de Percy, 1st Baron Percy, was in the train of William I. After arriving in England following the Harrying of the North (1069–70), he was bestowed modest estates in Yorkshire by Hugh d'Avranches. However, by the reign of Henry II the family was represented by only an heiress, Agnes de Percy (died 1203) following the death of the third feudal baron. As her dowry contained the manor of Topcliffe in Yorkshire, Adeliza of Louvain, the widowed and remarried second wife of Henry I, arranged the marriage of Agnes with her own young half-brother, Joscelin of Louvain. After their wedding, the nobleman from the Duchy of Brabant in the Holy Roman Empire settled in England. He adopted the surname Percy and his descendants were later created Earls of Northumberland. The Percys' line would go on to play a large role in the history of both England and Scotland. As nearly every Percy was a Warden of the Marches, Scottish affairs were often of more concern than those in England.

#### 1309: 1st Baron Percy

In 1309, Henry de Percy, 1st Baron Percy purchased Alnwick Castle from Antony Bek, Bishop of Durham. The castle had been founded in the late 11th century by Ivo de Vesci, a nobleman from Vassy or Vichy. A descendant of Ivo de Vesci, John de Vesci, succeeded to his father's titles and estates upon his father's death in Gascony in 1253. These included the barony of Alnwick and a large property in Northumberland and considerable estates in Yorkshire, including Malton. Due to being under age, King Henry III of England conferred the wardship of John's estates to a foreign kinsman, which caused great offence to the de Vesci family. The family's property and estates had been put into the guardianship of Bek, who sold them to the Percys. From this time, the fortunes of the Percys, although they still held their Yorkshire lands and titles, were linked permanently with Alnwick and its castle.

#### 1316: 2nd Baron Percy

Henry de Percy, 2nd Baron Percy, who was granted the lands of Patrick IV, Earl of March, in Northumberland, by Edward II in 1316, began to improve the size and defences of the castle. He was appointed to Edward III's Council in 1327 and was given the manor and castle of Skipton. Was granted, by Edward III, the castle and barony of Warkworth in 1328. He was at the siege of Dunbar and the Battle of Halidon Hill and was subsequently appointed constable of Berwick-upon-Tweed. In 1346, Henry commanded the right wing of the English Army which defeated a larger Scottish force at the Battle of Neville's Cross near Durham. His son, Henry de Percy, 3rd Baron Percy married Mary of Lancaster, an aunt of John of Gaunt's wife Blanche of Lancaster.

### 1377 creation

In 1377, the next Henry Percy was created Earl of Northumberland, a title given to him after the coronation of Richard II. He supported the takeover by Henry IV but subsequently rebelled against the new king, leading to his estates being forfeited under attainder. In his rebellion he was aided by his son, the most famous Percy of all, Henry "Hotspur", who was slain at Shrewsbury in the lifetime of his father. Both the 1st Earl of Northumberland as well as his son Hotspur play a chief role in Shakespeare's Henry IV.

### 1416 creation

Henry V restored Hotspur's son, the second Earl, to his family honours, and the Percys were staunch Lancastrians during the Wars of the Roses which followed, the third Earl and three of his brothers losing their lives in the cause.
The fourth Earl was involved in the political manoeuvrings of the last Yorkist kings Edward IV and Richard III. Through either indecision or treachery he did not respond in a timely manner at the Battle of Bosworth Field, and thus helped cause his ally Richard III's defeat at the hands of Henry Tudor (who became Henry VII). In 1489, he was pulled from his horse and murdered by some of his tenants.
The fifth Earl displayed magnificence in his tastes, and being one of the richest magnates of his day, kept a very large household establishment.
Henry Percy, the sixth Earl of Northumberland, loved Anne Boleyn, and was her accepted suitor before Henry VIII married her. He married later to Mary Talbot, the daughter of the Earl of Shrewsbury, but as he died without a son, his nephew Thomas Percy became the seventh Earl.
Thereafter, a succession of plots and counterplots—the Rising of the North, the plots to liberate Mary Queen of Scots, and the Gunpowder Plot – each claimed a Percy among their adherents. On this account the eighth and ninth Earls spent many years in the Tower, but the tenth Earl, Algernon, fought against King Charles in the Civil War. The male line of the Percy-Louvain house ended with Josceline, the eleventh Earl. The heiress to the vast Percy estates married the Duke of Somerset; and her granddaughter married a Yorkshire knight, Sir Hugh Smithson, who in 1766 was created the first Duke of Northumberland and Earl Percy, and it is their descendants who now represent the famous old house.
The current duke lives at Alnwick Castle and Syon House, just outside London.

## List of titleholders
### Earls of Northumberland, first creation (1377)

* Henry Percy, 1st Earl of Northumberland (1341–1408) (attainted 1405)
** Sir Henry Percy, also called Harry Hotspur KG (c. 1365–1403) heir apparent

* Henry Percy, 3rd Earl of Northumberland (1421–1461), (forfeit 1461), son of Henry 2nd Earl

### Earl of Northumberland, third creation (1464)

* John Neville, Earl of Northumberland, (1st Marquess of Montagu) (1431–1471), (1464–1470 released)

### Earls of Northumberland (1416, cont.)

* Henry Percy, 4th Earl of Northumberland (1449–1489) (restored 1470–1473), son of Henry 3rd

* Josceline Percy, 11th Earl of Northumberland (1644–1670), son of Algernon, died leaving only one daughter, so the Earldom became extinct
Various references use at least three different sequences of numbers for the Earls; the ones shown here are those used in the individual articles on the 12 Earls. The major difference arises from the question of whether Henry (1394–1455) was 1st as a new creation or 2nd as a restoration of the rights of his grandfather, Henry (1341–1408). Additionally, there is some debate about whether the 7th Earl was restored to the previous creation or was given a new creation.

### Earls of Northumberland, fourth creation (1674)

* George FitzRoy, Earl of Northumberland (1665–1716) (became Duke of Northumberland in 1683; extinct)

### Earls of Northumberland, fifth creation (1749)

* Algernon Seymour, 7th Duke of Somerset (1684–1750), female-line grandson and heir of the 11th Earl of the 1416 creation
** Elizabeth Percy née Seymour (1716–1776), only daughter of the 1st Earl, married Sir Hugh Smithson
* Hugh Percy, 2nd Earl of Northumberland (1714–1786), changed his name to Percy when he inherited the Earldom of Northumberland from his father-in-law by special remainder; became Duke of Northumberland in 1766
The line continues with the Dukes of Northumberland (third creation)
